This document describes adaptations and conversions of the existing CCSDS standard Space Link Extension (SLE) Return All Frames (RAF) space vehicle telemetry transfer service. Adaptations of RAF by the user and conversions of RAF by the provider provide standardized time-correlated telemetry and command echo services which are not otherwise provided by CCSDS SLE transfer services. Time-correlated telemetry service supports satellites which use unframed bit streams or bit streams without provider-side frame synchronization. Command echo service supports systems which require an independent check of provider RF equipment.
